PHP 4.4 and 5.1 Removed from Web Hosting

We have removed PHP 4.4 and PHP 5.1 from all our web hosting systems. PHP versions from PHP 5.2 to PHP 8.x remain available to you.

Why the removal was necessary

The reason is the current critical PHP vulnerabilities CVE-2026-109618 and CVE-2026-109619. According to CloudLinux, they can allow attackers to execute code without authentication under certain conditions.

Our DataDachs web hosting uses CloudLinux’s alt-php versions. CloudLinux has announced security fixes for these vulnerabilities in older versions as well, but only as far back as PHP 5.2. PHP 4.4 and PHP 5.1 are outside that range. Disabling them was therefore unavoidable.

What this means for your website

If your website previously used PHP 4.4 or PHP 5.1, please check your hosting’s PHP setting and your application’s compatibility with an available version. Where possible, choose a current PHP 8.x version supported by your software.

Our support team can help with questions about the change.
